Why is this medication prescribed?

Sedative chloral hydrate is used to reduce anxiety and induce sleep prior to surgery as well as for the short-term treatment of insomnia (to help you fall asleep and stay asleep for a decent rest). Additionally, it is employed to manage pain during surgery and alcohol withdrawal.

Ask your doctor or pharmacist for more details if you’re interested in using this drug for any other conditions.

How should this medicine be used?

Chloral hydrate is available as a suppository to insert rectally as well as a liquid and pill for oral use. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. As recommended, take the chloral hydrate. Never take it in larger or less amounts or more frequently than directed by your doctor.

Drink the mixture right away after mixing it with a half glass of water, fruit juice, or ginger ale.

Do not chew the capsule; instead, swallow it whole with a full glass of water or fruit juice.

To use the suppository, follow these steps:

  1. Take the wrapping off.
  2. Water should be applied to the suppository’s tip.
  3. Raise your right knee to your chest while lying on your left side. (If you are left-handed, you should lie on your right side and lift your left leg.)
  4. With the aid of your finger, place the suppository approximately 1/2 to 1 1 inch (1.25 to 2.5 centimetres) into the rectum of infants and children, and 1 inch (2.5 centimetres) into the rectum of adults. Hold it there for a short while.
  5. After about fifteen minutes, get up. Continue your regular activities after giving your hands a thorough wash.

Avoid taking chloral hydrate in higher doses, more frequently, or for longer than your doctor has prescribed because it has the potential to become habit-forming. Chloral hydrate should still be taken even if you feel OK. If you have been taking chloral hydrate at high doses for a while, you shouldn’t discontinue taking it without first consulting your doctor. Your dose will likely be gradually reduced by your doctor.

What special precautions should I follow?

Before taking chloral hydrate,

  • If you have an allergy to any medications, including aspirin, tartrazine (a yellow food and medicine colouring), or chloral hydrate, let your doctor and pharmacist know right once.
  • Inform your physician and pharmacist of all prescription and over-the-counter medicines you are taking, especially anticoagulants (also known as “blood thinners”) like warfarin (Coumadin), antihistamines, furosemide (Lasix), drugs for depression or seizures, sedatives, sleeping pills, tranquillizers, and vitamins.
  • If you have or have ever had kidney or liver disease, heart or stomach issues, a history of alcohol or drug addiction, or asthma, let your doctor know.
  • If you’re expecting a baby, intend to get pregnant, or are currently nursing, let your doctor know. Contact your physician right away if you find yourself pregnant while taking chloral hydrate.
  • Notify your doctor or dentist that you are taking chloral hydrate if you are having surgery, including dental surgery.
  • You need to be aware that this medication might make you sleepy. Until you know how this medication affects you, avoid operating machinery or an automobile.
  • Keep in mind that drinking alcohol can make the effects of this medicine even more drowsy.

An unpleasant stomach may result from chloral hydrate. Drink milk or eat while taking chloral hydrate.

What should I do if I forget a dose?

When you recall to take a missing dose, do not. Skip it entirely, and then take the following dose at the usual time.

What side effects can this medication cause?

  • Diarrhea

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it at room temperature and away from moisture and excessive heat (not in the bathroom). Don’t freeze; shield the liquid from light.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at for additional information.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Additionally, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Keep all of your doctor’s appointments.

Test your urine for sugar using TesTape or Clinistix if you have diabetes. Clinitest should not be used as chloral hydrate can result in inaccurate results.

No one else should take your medication. The substance chloral hydrate is under control. Only a limited amount of refills are permitted for prescriptions; if you have any doubts, speak with your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
